LAMP-BURNER.-

SPBCIFICATION'forming partof Letters Patent No. 365,739, dated June 28, 1887.

.To all whom, it may concern,.-

Bc it known that I, WILLIAM F. FOLMER, of Brooklyn, in Kings county'and State of New York, have invented a certain new and useful Improvementrin Lamp-Burners, of which the followingis a spceilcation.

In the accompanying drawings, Figure l is a vertical section of a lampburner embodying my improvement. Fig. 2 is a vertical section showing certain parts in a different position. Fig. 3 is a top View of certain parts of the burner, the wicktube tips, the wicks, the deileetors, and a chimneygallery being removed. Fig. 4 is a perspective view illustrating certain parts of a wick-carrier comprised in the burner. Fig. 5 is a perspective view of ecrtain modified parts of a wiclecarrier.

Similar letters of reference designate corresponding parts in all the gures.

A designates the body ofthe burner, consisting, as here shown, of a single struct-ure of cast metal, comprising parallel tubular portions a' ce2, intersected by passages a, of which three are shown extending from the inner tubular portion, ai, to the outer portion, a. This bodyn piece is open both at the top and bottom. It is secured within an air-distributer, B, which preferably will be made of sheet metal suitably perforated, of a cup or basket shape, and is provided at the lower end with a screwthrcadcd boss or bosses, whereby the burner may be secured to an oil reservoir or fount. The body may be secured in the air-distrib uter B by solder or otherwise.

O' C2 designate wick-tube tips, made of sheet metalwsneh as brass-and secured to the tubular portions a a2 of the body A of the burner. As shown, the wick-tube tip C2 is screwed onto the tubular portion a2, and the wick-tube tip O is screwed into the tubular portion a of the body A.

G designates a wick-carrier, comprising two rings, c c2, of sheet metal, one of which may be screwed into or out of the other, and one of which has secured within it aA cylindrical buriiingwick, D, and the other of which has secured in it strands of a feedingwicking, D.

The rings c'c2 and the feeding wick and wicking t within the wick-tube tips C O2 and the tubular portions a' a2 of the body A, the burning-wick extending up through the Wicletube tips when the burner is in use, and the wick extending down through the bottom of the burner into the oil reservoir or fount. The ring ol has secured to it rods c3 of wire. These rods extend downwardly through holes in the tops of the passages a3 of the body A, and are secured to arms c, which extend into the passages a of the body A from a tubular rod, c5, to which they are affixed. The tubular rod c5 is free to .move up and down upon a tubular guide, E, which is affixed to the bottoni ofthe body A of the burner.

The tubular rod c5 has in it, at one side, a number of holes, so that it is made to form a rack. A toothed wheel, F, engages with it. This toothed wheel is mounted upon a shaft, F', supported in bearings f, afiixed to the body A, and extending out through one of the passages ai of the body and through the air-distributerB, where it may be grasped by hand, 4for the purpose of operating it. By rotating the shalt in -one direction the wheel F may be made to elevate the wick-carrier, and by rotating it in the reverse direction the wick-carrier may be lowered. In this way the wick may be adj usted.

The tubular rod c5 on the side opposite to that along which it is perforated with helles to forni a rack has a slot formed longitudinally in it. The guide E, upon whrch this tubular rod tits, is provided with a siinilar slot. In the guide E a rod, G, is titted loosely, so that it may be raised and lowered therein. This rod is provided with a pin or arm, g, that eX- tends through the slot in the guide E and the corresponding slot in the tubular rod c5. On its upper end is mounted a button or spreader, H, whereby air, entering the air-distributer B, and passing thence through the passages a3 of the body A, and ascending the space wit-hin the tubular portion a2 of the body and the wick-tube tip GZ, is deflected outwardly against the inner surface of the flame. The rod G- constitutes a shank for the button or spreader.

I designates a bow-shaped lever, consisting, as here shown, of a piece of wire pivotally connected at the ends to the bearings f, in which the wick-adj usting shaft F is supported. Close to the ends of this bow-shaped lever it has bearings upon the Wick adjusting wheel F, at the sides ofthe teeth of the latter, said wheel IOO e fl 365,739

being shaped or` constructed so as to admit of this. Just beyond the portion of the bowshaped lever which bears upon this wheel the bow-shaped lever is bent upwardly, and then extends transversely across the tubular portion a of the body A and under the arm or pin g. At a certain portion in its circumference the wheel F, at the sides of its teeth, Vis provided with cavities f. Vhen this portion of the wheel is beneath the bow-shaped lever, lthe latter drops, and thereupon the rod G drops with it, so that the button or spreader H will descend upon the wick and extinguish the flame. Vhen the wheel Fis rotated i'nto a different position, it will raise the bow-shaped lever and elevate the button or spreader into the position which it is to occupy while the burner is in use. As the cavities inthe wheel are but of short extent, the wheel may be rotated for a considerable distance for the purpose of adjusting the wick without lowering the button or spreader H. j

I have shown arranged within the wick-tube tip O2 two perforated air-distributers, J J 2.

Mounted on the air-distributer B is a dellector, K, for directing air to the exterior surface of the flame, and the base ofthis delector is provided with a chimney-gallery, L. Between the wick-tube tip C and the detlector K air-distributers M M2 are arranged.

In Fig. 5 I have shown rings c c2 of modified construction for the wickcarrier. The ring c has a groove, r, formed lcircu mferentially in it. The ring o2 has not a deep upturned flange, as in the former example, illustrated more particularly in Fig. 4; but in lieu thereof it has a' number of upwardly-extending resilient fingers, r,which have transverse ribs r2. The ring c may be inserted between the ngers r of the ring c?, whereupon the ribs r2 of the latter will engage with its groove. It may be pulled out when it is tovbe separated. When the two rings are fitted together, the rounded lower portion of the ribs r2 will tend to force the ring c down into its proper place. The outer wick-tube tip, C', will, when in place, prevent the disengagement of the two rings c c2, .because it will prevent the lingers r froml moving outwardly.l

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a lamp-burner, the combination of a vertically-movable button or spreader, a shank y upon which said button or spreader is mounted,

a projection on said shank, a lever contacting with the projection for sustaining the button or spreader, a wheel for controlling the position of the lever provided with a cavity in its circumference,-and a shaft or journal upon which said wheel is mounted, which when rotated sufficiently far will bring the cavity in the wheel into such position that the lever will descend and allow the button or spreader to fall, substantially as specified.

2. Thecombination, in a lamp burner, of a wick-adjusting wheel having a cavity in its circumference, a vertically-movable button or spreader, a shank upon which said button or spreader is mounted, a projection on said shank, a lever contacting with said proj ectionY for supporting the button or spreader, and a shaft upon which said wheel is mounted,which when rotated a certain distance will cause the wheel to raise or lower the wick, butv which when rotated sufficiently far will bring the cavity in the wheel into such position that the lever will descend and allow the button or spreader to fall, substantially as specified.

3. The combination, in a lamp-burner, of a vertically-movable button or spreader,a shank upon which said button or spreader is mounted, a projection on the shank, a lever contacting with the projection for sustaining the button or spreader, a wheel for controlling the position of thelever, provided with a cavity in its circumference, a shaft or journal upon which said wheel is mounted, a wick-raising device, a rod with which said wick-raising device is connected, and a rack on said rod engaging said wheel, substantially as specified.

4. .A Wick-carrier comprising rings detachably secured together and attached to wicks, rods extending from one ot' the rings, arms attached to the lower ends of the rods and extending inward therefrom in a horizontal direction, and a rod to which the inner ends of said arms are secured, substantially asl specified. f

5. The combination, with a body-piece, A, having tubular portions a a2 and intersecting passages a3, of a wick-carrier, C, comprising a ring for attachment to a wick, rods extendingfrom the ring down through the tops of the passages a, arms attached to the lower ends of the rods and extending inwardly therefrom in a horizontal direction into the passages a3, and a rod to which the inner ends of these arms are secured, substantially as specified.

6. The combination of two interlocking wick-connecting rings, one provided with a groove and the other with ribbed resilient tngers, and mechanism connected with one of the rings for raising and lowering them both, substantially as specified.
